The apparatus comprises an activated carbon filter, a dehydration purifier, a first desulfurizer, a gas compressor, a de-oiling purifier, a second dehydration purifier, a buffer tank, a dehydration purifier group, a second desulfurizer, which are connected in order; and the second desulfurizer is connected to a membrane type gas separator. Through series of processing equipment, the apparatus provided by the invention separates impurities and gas mixed in biogas or natural gas; and the membrane type gas separator is used for separating methane and carbon dioxide in normal temperature state, so that purified methane content reaches 97-100%, and the purified methane can be directly used as a high-efficiency fuel for engines.
Description
Technical field
The present invention relates to a kind of portable purifying plant that utilizes gaseous diffusion process purification methane gas.
Background technology
Biogas is mainly by gas compositions such as 50%～70% methane and 30%～50% carbonic acid gas during without purification processes, and calorific value is generally at 20.16MJ/m
3～28.98MJ/m
3Between, energy density is low, can only use as domestic energy for a long time.The calorific value of highly purified methane (97%～100%) is 38.22MJ/m
3, can be used as oil substitutes directly as motor spirit.If can widen the Application Areas of China's renewable energy source biogas from common biogas and refuse embedded gas, obtaining high purity methane, solve the realistic problems such as vehicle fuel shortage.
Methane purification has four kinds of methods to realize at present, is respectively absorption process, pressure swing adsorption process, condensation at low temperature and membrane separating method.The absorption refining method is to utilize the physical chemistry absorption characteristic of By Amine Solutions and carbonic acid gas to realize.The Pressure Swing Adsorption method is to utilize the selective adsorption characteristics of sorbent material (as molecular sieve etc.) to carbonic acid gas, namely relative other gaseous components of carbonic acid gas have higher separation factor on sorbent material, reach the purpose that carbon dioxide in methane is removed.The cryogenic condensation method of purification is the characteristics of utilizing the co 2 liquefaction temperature high, by cold service, the carbonic acid gas in biogas is liquefied, and methane component is discharged with refined product gas as non-condensable gas.The membrane sepn method of purification is to utilize the gas with various component by the difference of membrane permeability effect, to realize under pressure-driven, the seepage velocity of normal conditions carbon dioxide is fast, as fast gas, discharge to see through gas, the seepage velocity of methane is slow, with saturating residual air form, obtains refined product gas as gas slowly.In industrial production, in order to improve the concentration of methane gas, often adopt the Using Multistage Membranes separating technology.
Membrane separation process, because the reasons such as technology maturity and economy are applied also seldom, particularly, on small-sized methane purification equipment, does not adopt membrane separation plant substantially.
Summary of the invention
The purpose of this invention is to provide a kind of portable gas purifying plant, be convenient to transportation, can carry out the purification processes of gas whenever and wherever possible.
For achieving the above object, technical scheme of the present invention is: the portable gas purifying plant, comprise the activated charcoal filter, dewatered clean device, the first devulcanizer, gas compressor, de-oiling cleaner, the second dewatered clean device, surge tank, dewatered clean device group, the second devulcanizer that connect successively, described the second devulcanizer connects the membrane type gas separator.
While adopting technique scheme, the present invention is by a series for the treatment of facility, by impurity and the gas delivery of mixing in biogas or Sweet natural gas, simultaneously, adopted the membrane type gas separator, under the normal temperature state, get final product separation of methane and carbonic acid gas, the methane content after making to purify reaches 97%～100%, can directly be used as the highly effective fuel of engine.
Further, the exit end of described membrane type gas separator has connected gas compressing apparatus.By gas compressing apparatus is set, can directly the gas after purifying be carried out to compressing and canning, realize storage timely, be convenient to transportation and use.
Further, the exit end of described the second devulcanizer has also connected reliever, and described reliever has connected gas engine, described gas engine-driven gas compressor and gas compressing apparatus.The marsh gas raw materials of preliminary treatment is used for to gas engine, then drives gas compressor and the gas compressing apparatus in equipment for purifying by gas engine, can gather materials on the spot, also can use at any time this equipment in the place that lacks fuel oil and electric power supply.
Further, for convenient transportation, body is arranged on the base plate with movable pulley.Above-mentioned design, can transport device by mode vehicle-mounted or traction, reach the purpose of portable transportation.
The accompanying drawing explanation
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of portable gas purifying plant embodiment of the present invention.
Embodiment
As shown in Figure 1, portable gas purifying plant of the present invention, pass into mixed gas, at first passes through strainer, and gac is housed in strainer, and the solid impurity in gas is carried out to Adsorption.Enter afterwards cleaner A, cleaner A is used for deviating from the moisture content of gas.Enter afterwards thionizer A, be used to the sulfurous gas of deviating to mix, as H
2S.Gas carries out supercharging by compressor A afterwards, after supercharging, enters cleaner B and deviates from the lubricating oil of gas through being mingled with after compressor A.Enter afterwards cleaner C, again dewater.Gas after dewatering enters in surge tank, and surge tank is for stored-gas, and in the maintenance purifying plant, air pressure is stable.From out gas surge tank, enter the cleaner group, for again deviating from moisture content.Enter again afterwards digester B, again deviate from sulfurous gas wherein.Finally enter membrane separation apparatus, the seepage velocity of fast air carbon dioxide is fast, discharges or carries out collection and treatment to see through gas, and methane obtains refined product gas as gas slowly with saturating residual air form.
Afterwards, the methane of purifying through membrane separation apparatus can collect by pressure reducer A and compressor B, for example can compressing and canning, conveniently transportation and use.Moreover, at thionizer B place, increase a pneumatic outlet, gas is through entering pressure reducer B after thionizer B, be used as again the fuel of gas engine A and gas engine B, wherein, gas engine A is for drive compression machine A, and gas engine B is for drive compression machine B, can not have under the prerequisite of exterior power input, only relying on the methane gas of rough purification to act as a fuel and supply with the whole system running.
Above-described is only the preferred embodiment of the present invention, should be understood that, for a person skilled in the art, under the premise of not departing from the present invention, can also make some distortion and improvement, for example, whole purifying plant can be arranged on the base plate with movable pulley, utilize vehicle traction or be directly installed on automobile, can conveniently transport, being transported to source of the gas ground whenever and wherever possible and carrying out purification.In addition, whole purifying plant can be arranged in the space of 8 cubic metres within, convenient transportation and transhipment, these also should be considered as protection scope of the present invention.
